Answer:
In terms of South African law, the Post Office is the only entity legally allowed to accept reserved mail and as such operates a monopoly.
Explanation:
The South African Post Office Group currently consist of a number of divisions and subsidiaries operating in the fields of mail, financial services, logistics, property, electronic commerce and retail services. Traditional collection, sorting and delivery of letters and parcels constitute the primary business activity of the group, responsible for nearly 65% of the groups revenue in 2010/12. In the 2010/11 financial year nearly 1,5 billion mail pieces were processed. To process and distribute this volume of mail items the group operates 6 large mail centres and more than 40 depots across the republic. The group has, however, suffered a decline in traditional mail volumes over the last 3 years. This decline is in line with similar declines experienced by the majority of postal operators across the world as traditional mail as a communication medium is substituted by electronic alternatives such as email and more recently cell phones.
The second largest activity of the group is financial services which it offers through its savings banks that operates under the name Postbank. The Postbank itself was formed in 1910 and is the largest savings bank in the country. More than 6 million customers have accounts with Postbank making it one of the largest banks in South Africa as measured by customer number. The Postbank is a deposit taking institution only, and thus does not offer credit products, only savings and investment products.
Answer: A. Slaves provided much of the labor on plantations that grew cash crops.
Plantations were the main economic activity in the American South during the antebellum period. These plantations cultivated cotton, tobacco, sugar, indigo, and rice. The warm climate, plentiful rainfall and fertile soil meant that the plantations were able to flourish. However, they were labour-intensive, and most workers were African slaves. Planters held dozens, or sometimes hundreds, of slaves, making slave labor very important to the economy of the Southern colonies.
Since the law of conservation of mass states that for any closed system the mass of the system must remain constant over time, the answer is that 18 grams of water will decompose to produce 2 grams of hydrogen and 16 grams of oxygen.
